<div class="htmlview paragraph">During the past few years, a new Flat Oval Tube Condenser has been developed (<span class="xref">1</span>) and launched in the market place (<span class="xref">2</span>) as a very strong and competitive alternative to the well known brazed Parallel Flow Condenser, due to its high performance and low cost.</div> <div class="htmlview paragraph">The Flat Oval Tubing used for this condenser application, seems very similar to traditional tubing used in Oval and Flat Oval Tube Radiators.</div> <div class="htmlview paragraph">However, due to higher pressure and pulsations when the A/C system is cycled on and off, it was very important to study fatigue properties to ensure a sufficient lifetime for Flat Oval Tube Condensers.</div>
